Methodology and limits
Attribution. Profiles are matched by federal identifiers or a high-confidence exact name, court, and service overlap. Assigned and referred matters are separated; this explorer shows assigned cases.
Filing cohort. Active and terminated counts describe cases filed inside the selected window as of its end. They are not a clearance rate or a measure of current workload.
Disposition cohort. Median time uses terminated cases from the same attributed assigned filing cohort shown in the selected window. It is withheld below 10 qualifying cases and excludes land condemnation, prisoner petitions, deportation reviews, recovery of overpayments, and enforcement of judgments.
No outcome claims. These data do not measure wins, losses, merits, judicial quality, or attorney success. Use the linked judge profiles and source records to verify legally significant information.
